Hi,

Welcome to the community!

We don’t support non-LTS versions of Java. Java 11 is the current LTS version of Java & it’s the latest version we support, as documented here.

Hi Pavel,

The SonarQube server support only LTS versions of Java (currently Java 11). But the code analyzers should be able to run with any Java version >= 11 (when you use a recent scanner).
In your case, the java analyzer raises an exception, but we don’t know on which java code. I’m able with SonarQube 8.5.1, to analyze a project targeting java 14 using maven-3.6 sonar:sonar and AdoptOpenJDK 14.0.2 without error.
Could you try to share a small reproducer of code that produces this NullPointerException?
Do you face the same error using SonarQube 8.7.0.41497?
